Multiple GPU Support

Hello everyone,

I am part of a high school engineering team, and we're trying to create a computing environment in which we can design and simulate an unmanned aerial vehicle. Virtual aerodynamics simulations are incredibly important, subsonic to hypersonic speeds, and we are trying to find a powerful hardware/software combination to accomplish this. We have decided that several AMD HD7990 GPUs have the highest compute performance for the price, and would like to know how we could leverage 7 of these GPUs to simulate aerodynamics in real time.
